There you go… An HDMI 2.0 capable media player may not be compatible with a HDMI 2.0 capable TV. HDMI Port 1 and 2 in LG UB8500 only support YUV420 for 60Hz which is not supported by RK3288. For example, LG UB8500 4K60p (60Hz) is tested working with Open Hour Chameleon with Deep Color turn on in HDMI Port 3. This configuration will also support advanced audio streams. This bandwidth allows for support of 4K video resolutions at a higher refresh rates with more detailed color information than previous HDMI specifications. – LG 55UB8800When set to 4K60p (60Hz), make sure the TV HDMI port support RGB444/YUV444 with Deep Color turn on. Maximum bandwidth in the HDMI 2.0 specification is 18Gbps. Here is a list of TV tested with 4K 60p settings so far:
#Hdmi 2.0 bandwidth driver#
4K 60p driver is in beta at this moment, we will include in the firmware when it is ready.
#Hdmi 2.0 bandwidth full#
Extract from Open Hour Chameleon FAQ: HDMI is 2.0 full version? or draft 8bit 4:2:0? Increasing the specification that far means that test and measurement. The current HDMI 1.4 specification tops out at 4K with 24 or 30 frames per second at 8-bit color. I’ve just found that Rockchip RK3288 processor allegedly does not support YCbCr 4:2:0, and only TVs with 10-bit color depth and YCbCr 4:4:4 or RGB 4:4:4 are supported. At this year's NAB several manufacturers confirmed that HDMI 2.0 will enable content up to UHD (2160p resolution) at 60 frames per second with 10-bit or maybe even 12-bit color. For example, before HDMI 2.0 came through there was HDMI 1.4, and its bandwidth was limited to just 10.2Gbps. That’s a major difference and one that’s significantly greater than any difference that came before. But there should not be compatibility issues, right? It’s just about quality? Wrong again. To put this into perspective, HDMI 2.0’s support only extended to 18Gbps bandwidth. That means those higher-end TVs can deliver more realistic colors via that HDMI port. But the higher models’ HDMI 3 port also supports 10-bit and 12-bit color depth, as well as other variations of chroma sampling up to YCbCr 4:4:4 or RGB 4:4:4.

Now let’s have a look at HDMI 2.0 capabilities of my TV (LG 42UB820T) against higher end model like UB850T.Īll models supports 3840 x2160p and 4096 x 2160p 50, 59.94, or 60 Hz, and 8-bit color depth, and YCbCr 4:2:0 chroma sampling. Higher bandwidth features, such as /60 (2160p) video formats, will require existing High Speed HDMI cables (Category 2 cables).
No, HDMI 2.0 features will work with existing HDMI cables.
